| opj_get_decoded_tile() where tile parts of a same tile are not consecutive This check was introduced per #939, but relied on the incorrect assumption we decode all the tile parts of all tiles. | |||

| 2017-09-05 | Add knownfailures-Ubuntu12.04-gcc4.6.3-x86_64-Release-3rdP.txt | Even Rouault | |
| For some reason, the OPJ_CI_ARCH=x86_64 OPJ_CI_BUILD_CONFIGURATION=Release OPJ_NUM_THREADS=2 configuration fails once PR1010 has been merged in master ( https://travis-ci.org/uclouvain/openjpeg/jobs/272219011 ) whereas (almost) the same code in my branch didn't fail per https://travis-ci.org/rouault/openjpeg/jobs/271738113 The errors we get are the same as with the other x86_64 compilers, so nothing alarming here. | |||

| indicate 1 again as being the value to get lossless for -r. In opj_j2k_setup_encoder(), make sure that ll rates[] <= 1.0 are set to 0. Document 0 as being lossless for -q / tcp_distoratio (#1009) | |||
| 2017-09-01 | opj_compress help: indicate 0 value, instead of 1, for -r parameter to get ↵ | Even Rouault | |

| 2017-09-01 | Tiny perf improvement in T1 stage for subtile decoding | Even Rouault | |
| 2017-09-01 | test_decode_area: accept user bounds in -strip_height mode | Even Rouault | |
| 2017-09-01 | Optimize opj_dwt_decode_partial_1() when cas == 0 | Even Rouault | |
| 2017-09-01 | opj_j2k_update_image_data(): avoid zero-ing the buffer if not needed | Even Rouault | |
| 2017-09-01 | Optimize reading/write into sparse array | Even Rouault | |
| 2017-09-01 | Allow several repeated calls to opj_set_decode_area() and opj_decode() for ↵ | Even Rouault | |
| single-tiled images * Only works for single-tiled images --> will error out cleanly, as currently in other cases * Save re-reading the codestream for the tile, and re-use code-blocks of the previous decoding pass. * Future improvements might involve improving opj_decompress, and the image writing logic, to use this strategy. | |||
| 2017-09-01 | opj_j2k_decode_tiles(): apply whole single tile image decoding optimization ↵ | Even Rouault | |
| to reading at reduced resolution as well | |||
| 2017-09-01 | Various changes to allow tile buffers of more than 4giga pixels | Even Rouault | |
| Untested though, since that means a tile buffer of at least 16 GB. So there might be places where uint32 overflow on multiplication still occur... | |||
| 2017-09-01 | TCD: allow tile buffer to be greater than 4GB on 64 bit hosts (but number of ↵ | Even Rouault | |
| pixels must remain under 4 billion) | |||
| 2017-09-01 | Fix compiler warning in release mode | Even Rouault | |
| 2017-09-01 | Remove limitation that prevents from opening images bigger than 4 billion pixels | Even Rouault | |
| However the intermediate buffer for decoding must still be smaller than 4 billion pixels, so this is useful for decoding at a lower resolution level, or subtile decoding. | |||
| 2017-09-01 | opj_tcd_init_tile(): fix typo on overflow detection condition (introduced in ↵ | Even Rouault | |
| previous commit) | |||
| 2017-09-01 | opj_dwt_decode_partial_tile(): avoid undefined behaviour in lifting ↵ | Even Rouault | |
| operation by properly initializing working buffer | |||
| 2017-09-01 | Sub-tile decoding: only allocate tile component buffer of the needed dimension | Even Rouault | |
| Instead of being the full tile size. * Use a sparse array mechanism to store code-blocks and intermediate stages of IDWT. * IDWT, DC level shift and MCT stages are done just on that smaller array. * Improve copy of tile component array to final image, by saving an intermediate buffer. * For full-tile decoding at reduced resolution, only allocate the tile buffer to the reduced size, instead of the full-resolution size. | |||
| 2017-09-01 | opj_compress: reorder checks related to code block dimensions, to avoid ↵ | Even Rouault | |

| later buffer overflow. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3115. Credit to OSS Fuzz. master only | |||
| 2017-08-28 | Make opj_set_decode_area() and opj_decode() take into account ↵ | Even Rouault | |
| opj_set_decoded_resolution_factor() (#1006, affect API use) * Better document usage of opj_set_decode_area(), ie expecting coordinates in full resolution/reference grid even if requesting at a lower resolution factor * Make sure that image->comps[].factor is set by opj_set_decode_area() and opj_decode() from the value specified in opj_set_decoded_resolution_factor() * opj_decompress: add 2 environmenet variables to test alternate ways of using the API, namely USE_OPJ_SET_DECODED_RESOLUTION_FACTOR=YES to use opj_set_decoded_resolution_factor() instead of parameters.cp_reduce, and SKIP_OPJ_SET_DECODE_AREA=YES to not call opj_set_decode_area() if -d is not specified. | |||
